Light reflections from the metal cause halation, making clear images of the text difficult. Even if the lighting is adjusted, halation occurs due to tilting or light interference during conveyance, making detection unstable.

The FQ Solution: High dynamic range processing prevents halation from metal even under near-natural lighting so that text can be clearly detected. The effects of changes in lighting caused by tilting or light interference during conveyance are also removed to enable stable detection.
